Abstract

Prior art limits the buttons on a mouse device to simple binary on/off. This invention extends this to variable pressure input, providing both digital and analog input. Several uses of analog input are also disclosed.

Pressure Sensitive Mouse

       Prior art limits the buttons on a mouse device to simple
binary on/off.  This invention extends this to variable pressure
input, providing both digital and analog input.  Several uses of
analog input are also disclosed.

      Existing mouse technology provides a simple digital on/off
signal.  This article discloses an improvement that also allows for
continuous range (analog) input.

      Replace the existing digital switch with any of several
standard strain instrumentation devices.  Using a low voltage signal
level this will allow the computer to use a software filter to
provide existing on/off states.  The preferred embodiment will be to
allow button movement with tactile click when the force exceeds the
digital cut-off.  Movement would provide greater resistance feedback
as well.  Optionally, the Workstation speaker could provide the click
indicating key action.  The value of this invention is the new
ability to provide a continuous signal.

      The default would be software filtered on/off.  The level of
sensitivity could be adjusted for user touch.  For programs that
exploit the analog capability, a visual indicator could be provided
as a reminder of analog mode.

      Prior art (industrial catalogs) has a wide variety of off the
shelf components covering a wide range of pressure, sensitivity, and
operating conditions.  Since this invention eliminates moveable parts
(the on/off switch) this mouse can...
